Sticker shock hit when I was looking for a 2 wire baffle grommet. $87 for 2 plastic grommets didn’t agree with my sense of reasonable. So I rolled my own with a little baffle seal and scrap aluminum.

Thought it was worth sharing for those that are having the same visceral reaction.

I am surprised that someone has not come up with a 3D printed version of that $87 part.
